VON' PEIN MACHINE OPERATING ONRECORD CARDS Filed Dec. 7, 1937 9 Sheets-Sheet 9 INVENTOR Patented Aug.8, 1939 UNITED STATES PATENT OFFICE MACHINE OPERATING ON RECORD CARDSApplication December 7, 1937, Serial No. 178,486 23 Claims. (Cl.164-112) This case relates to the system of automatic accountingemploying punched statistical record, or tabulating cards or forms.

' In this system, a card is punched in parallel columns to designateindicia or data according to a selected code. In the present case, theknown 'Hollerith code is used, each card column having index orperforation-receiving points assigned values 9 to 0 and a singleperforation in an index point of a column designating the value assignedto the punched index point.

The primary unit of the system is the punching machine which perforatesthe cards under manual or automatic control with the desired data.

Another, and previously separate, unit of the system is a verifyingmachine for checking a punched form with the data forwhich it wasintended to be punched, in order to determine whether an error has beenmade in the punching operation.

One of the objects of the present invention is to provide a single unitto selectively punch or verify a card.

Another object is to provide an improved punching machine includingmeans for interpreting or printing the significance of the perforationsof the card.

The latter object contemplates provision of a single punch for punchingany index position in any column of a record card.

A further object is to provide improved power means for carrying througha manual selection to punch or verify a card.

Another object also is to provide improved verifying means.

Further objects of the instant invention reside in any novel feature ofconstruction or operation or novel combination of parts present in theembodiment of the invention described and shown in the accompanyingdrawings whether within or without the scope of the appended claims andirrespective of other specific statements as to the scope of theinvention contained herein.

As indicated in Fig. 1, the tabulating card T has parallel columns ofindex points or perforation-receiving positions. There are ten digitalvalue positions 9 to 0 in each column. In addition, each column has 11and. "12 positions successively above the 0" positions, perforations inwhich are used to control machine operations, particularly in otherunits, such as the tabulating machine unit, of the accounting system.

The present machine has provisions for punching blank cards I in any ofthe 9 to 0 or 11 and 12 positions. The latter two positions are usuallynot interpreted; that is, a printed conventional designation ofpunchings in the 11 and 12 positions is not provided. Conforming to thisusual practice, the present machine has means to interpret only the 9 to"0 perforations by printing at the top of the column the conventionaldigital representation of the punched hole of the column. It may benoted. also, that the "11" position is customarily referred to and willbe referred to hereinafter, as the X" position.

The machine comprises a main base frame l6 having a top, flat plate Ilato support a card T. Top plate Ila carries an intermediate framemounting for vertical, slidable, movement a series of designation keys|20 to 9, X, 12 for initiating punching of index positions to 9, X, or12 of a card column. A space key |2--S and a release key |2R are alsoprovided, respectively to initiate a column space operation and acarriage release operation. Referring to Figs. 1, 6, 15, and 11, eachkey I2 is pivotally connected to one end of an intermediately pivotedlever i3, the opposite end of which pivotally suspends a vertical slide|4 guided for vertically slidable movement by comb bar l5 and bracket l6fixed to the front plate ll of the frame. The lower, rearwardly bent end4a of slide l4 extends outside frame plate l1 and between the beveledends of a pair of straddling stop arms l9 (also see Fig. 18). When a key2 is depressed, acting through lever l3, it raises slide l4; againstresistance of a spring 26, causing the lower end |4a of the slide tospread the straddling stop arms I9 apart. crowding the remaining stoparms together to prevent coincidental depression of any other key.

Near its lower end, the slide 4 01' each designation key |2 is formedwith an inclined cam edge I 4b, (Figs. and 17) leading inwardly andupwardly to Join a notch |4c having a square upper shoulder. Hooked intonotch Me of each vertical slide I4 is the rear, bent tab 2|a of ahorizontal slide 2| (also see Fig. 9), guided by bracket l6 and a combbar 22 for horizontally slidable movement, but which permit lifting ofthe bar. A spring 23 urges horizontal bar 2| forwardly, or to the rightas viewed in Fig. 15 to maintain its rear end 2|a within notch 0 of theassociated vertical slide |4 when the latter is in normal position,shown in Fig. 15. The right or forward end of each horizontal bar 2| isformed with a hook 2|b latched over a lug 24a of a latch lever 24 freelypivoted on a shaft 25. There is one lever 24 for each bar 2]. On shaft25 is fixed a bail 26 urged clockwise (Figs. 15 and 17) by a spring 21and having a cross rod 26 commonly engaging all the latch levers 24 tomaintain the latter against a common stop rod 29. As shown in Fig. 10,shaft 25 rigidly carries an arm 36 having a pivot stud 3| to mount aby-pass pawl 32 urged by a spring 33 to engage its tail with a pin 34fixed to arm 30. The nose of pawl 32 is above the tail of a latch 35held by a spring 36 in hooked engagement with the tail of a clutch dog31 carried by a driven clutch disk 36 (also see Figs. 9 and 19) fast toa cam shaft 49. Rotatably carried by shaft 46, and adjacent clutch 33,is a driving ratchet 4| rigid with a gear 42 rotated through a helicalgear 43 from a pinion 44 on a shaft 45 continually driven by a motor M(Fig. 10) through gearing 46.

Upon depression of a designation key |2, its lever l3 raises connectedslide l4, causing cam edge |4b to cam against the tab 2|a of horizontalslide 2| moving the latter rearwardly, as indicated in Fig. 17. Sincehook 2|a of bar 2| is then engaged with lug 24a of the companion latchlever 24, the rearward movement of the effects counterclockwise actionof the l tch lever. The latter, in turn, through engagement with bailrod 23, swings ball 26 and its shaft 25 counterclockwise, these actionsof the latch lever and the bail and its shaft being commonly resisted byspring 21. As shaft 25 rocks counterclockwise, its arm 33 (see Fig. 10)moves down, and dog 32 on this arm strikes the tail of latch 35 torelease the latter from clutch dog 31. The clutch dog, thereupon,engages the teeth of continually rotating driving ratchet 4|, couplingthe latter to driven disk 38 which carries the clutch dog. Accordingly,cam shaft 40, on which disk 33 is fast, is now coupled to the drivingmeans for rotation.

The extent of downward movement of arm and the dimensions andarrangement of arm 30, its dog 32, and latch are such as to cause dog32, after releasing latch 35 from clutch dog 31, to ride past the tailof latch 35. Spring 36 thereupon returns latch 35 to its normalcounterclockwise position, indicated in Fig. 10, in which its head is inposition to intercept the tail of clutch dog 31 when cam shaft has madea single revolution. Thus, the depression of a key l2 results in only asingle revolution cycle of cam shaft 40. During return, clockwise, ofarm 30, which is effected subsequently to by-pass dog 32 moving downpast the tail of latch 35, the by-pass dog, being permitted to rockcounterclockwise relative to its carrying arm 30, ratchets past the tailof latch 35.

When latch lever 24 moved counterclockwise its upper end withdrew itssupport from a coupler pawl 46 (Figs. 15 and 1'7) pivotally carried by abell crank 49 at the right hand end of the horizontal arm of the bellcrank. There is one such bell crank 49, and pawl 48 carried thereby, foreach latch lever 24, and the bell cranks 49 are rotatably carried by acommon shaft 50. Pawl 48 is urged counterclockwise relative to itscarrying arm by a spring 5| between the arm and the pawl. Upon releaseof the pawl by latch lever 24, this spring 5| rocks the pawlcounterclockwise, causing a notch 43:: thereof to clasp the commoncoupler cross bar 5211 carried between sides 52b of a coupler bail 52rotatably mounted on shaft 56 (also see Fig. 9). In thiscounterclockwise position of pawl 48, the free end of the horizontal armof the pawl is at the right of its companion latch lever 24 and untilthe pawl moves upwardly away from the latch lever, the latter is held bythe horizontal arm of the pawl against return clockwise action.

Directly underneath each hook bar 2| is a companion lock bar 53. Whenpawl 48 rocked counterclockwise, its lower arm, initially abutting theright end of the associated lock bar 53, as indicated in Fig. 15,withdrew from the latter, enabling a spring 54 to move the lock bar tothe right, thereby seating its left, bent end 53a in a square notch |4dof the associated, raised, vertical slide l4, as indicated in Fig. 17.Accordingly, that slide H which has been raised by depression of a keyI2 is now locked in raised, operated position, even after the operatorreleases the key, by coaction' of bent end 53a of lock bar 53 with notch|4d of the slide. When lock bar 53 moves to the right, a cam projection53b thereof coacts with the left side of a reverse cam projection 2 c ofthe companion hook bar 2| to raise the latter, thus lifting hook 2| bthereof clear of lug 24a of the associated latch lever 24, as indicatedin Fig. 17. The latch lever, however, is still held against clockwisereturn movement, by engagement with the end of the horiand provided witha roller 56:: projecting into for counterclockwise action, thehorizontal arm of the latter then moving down and against the right sideof the upper arm of lever 24 to temporarily restrain return in aclockwise direction of the latter, while the notch 48a of the pawlgrasped the common coupler bar 52a.

, One of the sides 52b (Fig. 15) of coupler bail 52 has a rearwardextension connected by a link 55 to an arm 56 rotatably carried by a rod51 a box-cam groove 58a of a cam 58 fixed to cam shaft 40.(also seeFigs. 9 and16). As shaft 48 rotates, cam groove 58a moves arm 56downwardly, which through link 55 rocks coupler bail 52counterclockwise. As a result, the coupler pawl 48 which corresponds tothe depressed key and is now coupled to bar 52a of coupler 52, is movedupwardly by the rising bar 52a, causing counterclockwise movement of thebell crank lever 49 carrying this particular pawl. The lower end oflever 49 has a roller 49a extending into a triangular hole 68a of a camplate 68 fixed to a shaft 6!. The upper and lower sides of thetriangular hole taper towards a restricted apex slot 6% adapted tosnugly receive roller 49a at theend of the counterclockwise, or forward,stroke of lever 49. There is one cam plate 60 for each lever 49, andtherefore, for each designation key. The triangular holes 60a are formedwith different apex angles with the apices of the different cam platesbeing differentially located with respect to the common shaft 6|. When alever 49 moves through its forward stroke, roller 49a thereof will camagainst the upper or lower edge of the cam hole 60a of the associatedcam plate 68, rocking the latter until, at the end of the forwardstroke, the roller is seated in the apex. This action results in thepositioning of cam plate 68 at a predetermined angle, regardless of theangular position which the cam plate may have had at the beginning ofthe forward stroke. Each lever 49 thereby, will set the associated camplate 68 at a definite angle differentially related to the predeterminedangular positions at which the other cam plates may beset by theirrespective levers 49. As a cam plate moves to its predetermined angularposition, it rocks common shaft 6|, to which the cam plates are fast, toa corresponding position. Fixed to the left of shaft 61 (see Figs. 4, 6,l5, and 17) is an arm 62 having a slot in its upper end receiving a pin63 of a punch and type slide 65. As shaft 6| moves to its predetermineddifferential position, its arm 62 shifts slide 65 transversely of thelength of the machine to a corresponding differential position (also seeFigs. 1, 2, 3, and 8).

Referring particularly to Figs. 4 and 8, the punch slide 65 has a cardslot 65a extending lengthwise of the slide and the lower edge of theslot is flush with the card supporting surface of top frame plate Illa.The length of card slot 65a is such that in either of the extremedifferential positions of the punch slide, the ends of the slot will notengage with the sides of a card T resting on top plate Illa between thesideguiding shoulders Nb of the top plate.

The punch slide 65 is guided for horizontal sliding movementtransversely of the machine by dowel screws 66 secured to key-mountingframe II and passing through elongated slots 65b of the punch slide.Additional guiding for the punch slide is provided by engagement of thesides of the die portion 650 of the punch slide with the opposite sidesof a transverse channel We formed in frame 10 (particularly see Fig. 6).Die portion 65c is below card slot 65a and the top of the die portion isin the plane of card supporting top plate Illa, and bridges the channel100, so that a card may move smoothly from the portion of top plate Illato the right (as viewed in Fig. 6) of the channel, across die 65a and tothe portion of the plate to the left of the channel.

Die 650 has a die hole 65d (see Fig. 12) to receive a punch 61 ofrectangular cross section (see Fig. 3) after the latter has passedthrough the card and made an elongated perforation therein. Punch 61 isvertically slidably mounted in the portion of the punch slide above cardslot 65a. The upper end of the punch has a transversely extending pin61a (see Figs. 12 and 13) resting on the forwardly protruding depressedangular lip 68a of a stripper plate 68. In the normal clockwise positionof the stripper (as viewed in Fig. 13), the lip 68a maintains the punchclear above the card plane. When the punch slide is in 0 position, punch61 and die hole 6511 are at opposite sides of the 0" index position of acard column, as indicated in Figs. 1 and 4. Depression of a designationkey l2, sets the previously described train of operations in effect forshifting the punch slide transversely of the machine. The extent ofshifting of the punch slide depends on the cam plate 68 which isoperated, and the operation of the cam plate is ofsuch extent and insuch direction as to position the punch couple 61-65:: at the card indexposition corresponding to the depressed key.

, Thus, with the punch slide at 0 position, assume the 1" key l2-I isoperated. Through its lever I3 (see Fig. 15), the key raises connectedvertical slide l4, causing incline 14b of the latter to cam the enactinghook bar 2la to the left. Hook end 2!?) of bar 2| thereupon acts on lug24a. of latch lever 24 to rock the latter, the bail rod 28 engagedtherewith, bail 26, and bail shaft 25 against resistance of spring 21.As a result, the upper end of lever 24 releases coacting coupler pawl 48to enable spring M to rock the pawl counterclockwise, coupling it tocoupler bar 52a. As the pawl rocks counterclockwise, its lower endpermits spring 54 to move lock bar 53 to the right, bringing its leftend into notch Md of slide l4, locking the latter in raised position.Further, cam portion 53b of bar 53 acted on cam 2lc of bar 2! to raisethe latter, lifting hook 2!!) clear of lug 24a, but the latterjs nowretained in counterclockwise position by engagement with the horizontalarm of pawl 48. Also, when bail shaft 25 moved counterclockwise its arm3|] caused the clutching of cam shaft 48 to the driving means, aspreviously described. Now, as cam 58 on shaft 40 rotates, it acts onlinkage 56-55 to rock coupler 52 counterclockwise, which through theinterlocked bar 52a and pawl 48 similarly rocks the lever 49 on one endof which the pawl is mounted. As lever 49 rocks to the end of itsforward or counterclockwise stroke, indicated in Fig. 1'7, the roller49a moves into the III apex slot 80b of the associated cam plate 88 and,in its course, cams against a side of the triangular hole 88a in the camplate to rock the latter a differential amount. Shaft 8|, to which allthe cam plates 88 are fast, is thereby rocked the differential amountdetermined by coaction of one of the cam plates with the associatedlever 48 which has been coupled to the coupler bail 52. The other levers48 are in initial position and their rollers 48a are within the wideportions of their respective holes 88a, so that all the cam plates mayfreely rock with shaft 8| in accordance with the actuation of one camplate by the lever 48 coupled to coupler 52. As shaft BI is rocked tothe selected differential position, its arm 62 coacts with pin 83 ofpunch slide 85 to move the latter one step to the right (as viewed inFig. 4). The actuated lever 48 having rocked the associated cam plate 88by action of roller 49a to a differential position, the roller, andconsequently lever 48, may return, with no effect on the cam plate, toits initial position as the cam shaft 48 and its cam 58 complete theircycle. Thus, shaft GI having been set in a position corresponding to thedepressed key, will remain in this position until a differentdesignation key is operated.

In above manner, depression of a "1 key I2 has moved punch slide 85 from0" position to the "1 position for perforating the 1" index pointposition of a card column. The punch slide remains in this positionsince cam bars 88 are not restored to a home position. When the nextdesignation key is depressed, it causes the punch slide to move from itsprevious key selected position to the position corresponding to thenewly depressed key. Thus, depression of key I2-9 will shift slide 65 tothe right to move the punch couple from its previous 1" position to the9" index position.

Incidentally, when coupler 52 elevated coupler pawl 48 to rock itscarrying lever 48 counterclockwise, the horizontal arm of the pawlwithdrew from restraining engagement with the associated lever 24, whichis thereupon returned clockwise by the common spring 21, acting throughball 26, its shaft 25 and bail rod 28. As shaft 25 returns clockwise,its arm 88 (see Fig. 10) moves in the same direction and by-pass dog 82ratchets past the tail of lever 35 and back to its initial position,ready for the next cycle of operations.

When punch slide 85 is shifted to a key-selected position, its punchcouple is definitely alined and located with respect to the selectedindex position of the card column. For this purpose, an aligning rack18, (see Figs. 1, 2, 11, 14, 15, and 17), fastened to the punch slide,has a notch 10a (Fig. 15) for each of the twelve possible positions 9,8, 1, 8, 5, 4, 3, 2, I, II, X or II, and I2 01' the punch couple. Camshaft 48 has a cam 1| (Figs. 9, 15, 16, and 17) engaging a pin 12a onplate 12 pivotally carried by rod 51. The plate is connected by a link13 to a bell crank 14, the right hand end of which has a tooth 14a toseat in any of notches 180. As indicated in the timing chart Fig. 21,after cam 58 causes shifting of the slide 85 to the key-selectedposition, cam 1| actuates plate 12, which through link 18, rocks lever14 to cause tooth 14a to enter a notch 18a of bar 18, thereby lockingthe punch slide and definitely placing the punch couple in registrationwith the selected index position. The punch slide is locked in theselected position during either verifying or punching and printingoperations, after which tooth 14a is moved out of the notch 18a by aspring 14' to release the slide.

In addition to the punch 61, the upper part of punch slide 65 alsocarries a column of; ten type bars 15-0 to 9 (see Figs. 1, 3, 4, and 8).The type bars are normally raised above the card plane by individualsprings 18 (Fig. 4). Under the column of types is a rubber platen 11carried by the part of the punch slide below card slot 65a, and the topof which lies in the common plane of punch die plate 65c and topcard-support plate Illa. Platen 11 bridges a portion of transversechannel Illc in plate Ila. (as indicated in Figs. 11 and 14) to enablethe card to move smoothly across the channel.

With a card column in position in card slot 65a of the punch slide,adjustment of the punch slide locates the punch couple 6165c at theindex position selected by a depressed designation key I2 and alsosimultaneously locates the type bar 15 corresponding to the indexposition at the top of the card column. Thus, when a. key I2-8 isdepressed, slide 65 is shifted to bring the punch couple to the 8 indexposition .of a card column and the type 158 to the printing position toprint character 8 at the top of the card column, the printed characterinterpreting the punched code designation of the column.

While the punch slide 65 is being shifted to select an index positionfor the punch couple, the upper pin 61a of punch 81 rides on lip 68a ofstripper plate 68, while the upper end of the punch rides along thebottom of a pressure plate 88 (see Figs. 1, 2, 3, 4, 6, 12, and 13) heldon stripper plate 68 by guide studs 8| fixed to the latter and extendingthrough an elongated slot 88a of the pressure plate. This mountingpermits slidable adjustment of the pressure plate on the stripper platein a direction transverse to the length of punch slide 85 for a purposewhich will be made clear hereinafter. The pressure plate 88 and stripperor restoring plate 68 may be referred to collectively as the punchoperating assembly.

Extending upwardly from pressure plate 80 are two pins 82 (Fig. 1),between which is disposed the eccentric portion 83a of a stud 83,rotatably mounted in the cover Ila of key frame II and provided abovethe cover with a knob 84 (also see Fig. 6). Knob 84 has an index 84a forpointing either to the legend Verify" or the legend Punch and interpret"marked on cover Ila. By rotating knob 84 to the "Punch and interpret"position, eccentric 83a coacts with pins 82 to shift pressure plate 80forwardly to locate the forward portion of the pressure plate in anoperating position above punch pin 81, as indicated particularly inFigs. 12 and 13, and to locate a hammer portion 88b (see Fig. 4) of thepressure plate above the type 15 at printing position. By turning knob84 to the Verify" position, pressure plate 88 is retracted to anonoperating position, indicated in Fig. 7, in which its forward portionis removed from above the punch pin and its hammer portion 88b fromabove the type at printing position.

Assuming knob 84' is in the Punch and interpret position, pressure plate88 is in operating position. Initially, the pressure and stripper plateassembly 8888 is in clockwise position (Figs. 6 and 13). Duringadjustment of punch slide 65, the top of punch 81 rides on the bottom ofpressure plate 80 while the pin 81a of the punch pin rides on lip 68a ofstripper plate 68. Stripper plate 8 is formed with downwardly bentopposite sides or arms 68b rockably mounted on a shaft 85. The righthand arm 6% (as viewed in Fig. 4) is plvotally connected to the upperend of a link 86 (also see Fig. 6), the lower end of which is connectedto acam follower lever 81, having a roller 81a. following a cam 88 ofcam shaft 40 (Figs. 4, 6, 9, and 16).

As indicated by Fig; 21 (the timing chart), after cam 58 has adjustedslide 85 to the keyselected position and after cam H has caused thelocking of the slide by alining lever 14, then cam 88 rocks lever 81 toreciprocate link 86 for oscillating the punch-operating assembly 687-80.

During the down stroke of the latter assembly,

pressure plate 80 presses on the top of punch 61, depressing it toperforate the selected index point of the card column at punchingposition, while, at the same time, hammer portion 8012 (Fig. 4) of thepressure plate strikes the head of the type 15 at printing position andeffects printing thereby, at the top of the column, of the figurecorresponding to the perforation. During the return stroke of thepunch-operating assembly, lip 88a of the stripper plate engages pin 61aof the punch to strip the punch from the card and restore it to elevatedposition.

Card feed The cards T to be punched are stacked on top of the frameplate Na in a magazine 90 at the right (as viewed in Figs. 1 and 6) ofthe key frame II. Thecards lie in the magazine with their columnsextending across the width of the machine and with the index points 9-0,II, I2 disposed as shown in Fig. 1. Just behind the rear edge of thebottom card in the magazine is the feeding shoulder of a picker 9I (seeFigs. 1, 6, and 10) carried by a slide 92 guided on fixed rods 93 forhorizontally slidable movement below maga- Zine 90. Pivoted on stud 96to the side of slide 92 is a U-shaped bracket 95. The upper leg 95aofframe 95 is rigid with an upper, horizontally extending picker rack 96and the lower leg 951) with a lower horizontal picker rack 91.

Between racks 96 and 91 is a gear 98 (also see Fig. 19) fixed to one endof a shaft I journaled in the frame. Gear 43,, in the transmissionbetween motor driven shaft 45 and cam shaft 40, as previously described,is rigid with one end of a sleeve IOI rotatably carried by shaft I00. Tothe opposite end of sleeve MI is fixed a driving ratchet gear I02adjacent a driven clutch disk I03 rigid with a collar I04 fast to shaftI00 (particularly see Fig. 10). Disk I03 carries a clutch dog I05normally latched in inactive position relative to driving ratchet gearI02 by an arm I060 of a three-armed latch lever I06 urged clockwise intolatching position'by a spring I06. An arm I06b of latch lever I06 isunder one end of a lever I01 pivoted at I08 to the frame and having itsopposite end above the reduced end I09 of a slide bar I09. In back ofthe reduced end I09, a bar I09 has a beveled, cam portion I09a (also seeFig. 20) which upon advance, or movementto the right (Fig. 19) of theslide bar cams the right end of lever I01 upwardly (Fig. 10). slide barI09 (Figs. 19 and is pivotally connected to a lever IIO pivoted to theframe and carrying a by-pass dog III which is in the path of movement ofthe right hand end of an escapement rack II2. A spring II3 connected tolever I I0 holds it in clockwise position (Fig. 19), thereby maintainingslide I09 in rear position, with its cam edge I09a in back of and itsre- The rear or left end of duced end I08 under lever I01. Rack bar H2is mounted on the frame I0, in the manner usual in similar types ofpunching machines (see Patent 1,772,186) for lengthwise movement and isrigidly provided with a transverse arm Ill (Fig. 1) at the left endprovided with a thumb piece II5 (also see Fig. 6) and carrying anabutment II6 for the left hand or leading end of the card.

A parallel arm II1 (Figs. 5, 11, 14, 19, and 20) rigid with rack II2extends above top plate IM and pivotally carries a card clamp andabutment H8 for engaging the rear or lag g end of the card. The rackII2, arms I and H1 and the card abutments H6 and H8, between which thecard is to beconilned, constitute a card carriage for feeding the cardalong top frame plate I00 and past punching slide 65.

The upper edge of rack H2 is formed with escapement ratchet teeth II 2aand the lower edge of the rack with plain teeth II2b (Figs. 11 and I4).The lower teeth mesh with a gear II9 driven by a spring motor M (seeFig. 14), as is usual in this type of column-by-column card punch.

Initially, a bump 91a (Figs. 6 and 19) of lower picker rack 91 isresting on top of a leaf spring I20 thereby maintaining bracket 95 inclockwise position about pivot stud 94, with the lower rack in mesh withgear 98 and upper rack 96 out of mesh. Above bump 91a, a rack 91 isprovided with a transversely extending pin I2I now being held by springI20 with its center above the upper surface of a fixed, horizontal trackI22.

At the end of the punching of the previous card, escapement rack H2 isat the extreme left (Fig. 19). To place a new card in the carriage II2-II6--I I8, the operator now pushes on thumb piece II5 of the cardcarriage to manually move the carriage through its card receivingstroke, towards the right. After a short travel, in this direction, ofrack II2, the right hand end of the latter engages the by-pass dog IIIof lever H0, and continued movement of the rack effects counterclockwiserocking of the latter lever, causing advance of connected, slide I09during which the cam edge I09a of the latter lifts the right end oflever I01. to cause the latter to rock counterclockwise (Fig. 10). Theleft, lower end of lever I01 thereupon bears down on arm I06a of latchlever I06. to rock the latter counterclockwise (Fig. 19), releasing itfrom clutch dog I05 which thereupon engages driving clutch gear I02,thus coupling disk I03 and its shaft I00 to driving sleeve IOI (Fig.10). Gear 98 on shaft I00 is now being rotated, while the card carriageis continued by the operator on its card receiving stroke. When latchlever I06 was rocked counterclockwise to release clutch dog I 05, thetop of its vertical arm I 060 moved from under an arm I of a shaft I26,permitting a spring I21 to rock the arm I25 downwardly to engage theright side (Fig. 19) of arm 1060 for locking latch lever I06 inactuated, counterclockwise position. A

Rotation of gear 98 is in a clockwise direction (Figs. 1 and 19),thereby coacting with meshed lower picker rack 91 to move frame 95 andconnected picker slide 92 with its picker 9I through the forward stroke,or to the left, opposite to the direction in which the card carriage isbeing moved by the operator. Before bump 91a leaves spring I20, pin I2Iof picker rack 91 rides onto the top of track I22, and the coaction ofthe pin and track continue to maintain the lower picker rack in meshwith gear 98 for the remainder of the forward stroke of the picker II.During the forward stroke, picker II engages the rear edge of the bottomcard T in magazine 90 and feeds this card through throat 300 (Fig. 6)and under the rear card abutment and clamp II8 of the card carriage. Atthe end of the card receiving stroke of the card carriage, escapementrack H2 is at the extreme right, and picker 3| has completed its forwardstroke and'fed the card into a position with its rear or lagging edgeunder rear card clamp Ill, in the same manner fully disclosed in Patent1,772,186. The card is now delivered to the carriage, and is resting ontop plate Ia, with its sides between ledges I 017 of the top plate, itsforward or leading edge abutting front abutment H6 and its lagging edgeengaged with and abutting rear clamp H8. The first card column of thecard in the card carrlage is then at punching position within card slot65a of punch slide 65.

As the picker mechanism nears the end of the feed or forward stroke, acam bump 96a of upper picker rack 96 rides under a bowed spring I28(Fig. 6) and at the same time pin I2I of lower picker rack 91 rides offrail I 22. As the picker mechanism finishes its feed stroke, thecoaction of spring I28 with cam bump 96a forces the picker rack assemblyto rock counterclockwise about its pivot stud '94, thereby meshing upperrack 96 with gear 98 and demeshing lower rack 91 from the gear. Further,in this position of the picker rack assembly, pin I2I of lower rack 91is below the plane of track I22.

Just as the picker assembly completes its feed stroke, a projection 91b(Fig. 6) at the right end of upper rack 96 engages an arm I29 of shaftI26 and rocks this shaft clockwise. Arm I25 of shaft I26 thereupon risesand clears the side of arm I060 of latch lever I06, permitting thelatter to be returned clockwise by spring I06. The operations of theparts are so timed that before the latch lever fully returns to normalposition, gear 38 has completed one revolution and the tail of clutchdog I has already passed the hook end of arm I06a of the latch lever.The latter thus fails to intercept dog I05, and the dog remains coupledto driving ratchet I02, causing gear 98 to make a second revolution atthe end of which dog I05 is intercepted by latch lever I06, therebyinterrupting rotation of gear 98. Thus, gear 98 makes two continuousrevolutions for each new card fed to the card carriage.

At the end of the forward or feed stroke of the picker assembly, springI28 is engaging bump 96a of upper rack 96, the latter has thereby beenmeshed with gear 98, and pin I2I of lower, now demeshed, rack 81 isbelow track bar I22. As upper rack 96 is meshed with gear 98 during thesecond revolution of the gear, the card picker assembly is now moved tothe right, through its return stroke. Before bump 96a. leaves springI28, pin I2I of the lower rack moves under track bar I 22, and coactionof the pin with the bottom of the track now continues to hold the pickerrack assembly in counterclockwise position about pivot stud 94, withupper rack 96 in mesh with gear 98. The second revolution of the latterreturns the 'picker assembly to starting position and at the end of thereturn stroke, pin I2I leaves track bar I22 and spring I again coactswith bump 91a to restore lower rack 91 into mesh with gear 88.

Column-by-column card feed During the manually effected forward or cardreceiving stroke of the card carriage II2--I I6-- II8, lower spur teethII2b of escapement rack II2 rotated gear H3 to energize spring motor M(Fig. 14). Coacting with upper, ratchet teeth Il2a of rack H2 is aholding dog I32 (Figs. 1, 9, 11, and 14) normally engaging a tooth I Into restrain actuation of the escapement rack towards the right (asviewed in Fig. 11) by spring motor M. Dog I32 is pivoted on a shaft I33mounted between the sides of frame I0 (see Figs. 4 and 9) and to whichis fast a double arm member I34 having a pin 134a on one arm extendinginto a hole in the holding dog and a pin I341; on

the opposite arm extending into a slot in an escapement pawl I35. Thenose of pawl I35 in the released position of the pawl (see Fig. 11) isabove the interdental notch between a pair of consecutive teeth II2awhile dog I32 is engaging the abrupt end of a tooth, being normallyurged against the rack by a spring I36 between member I34 and the dog.Referring to Figs. 4 and 9, to an intermediate portion of shaft I33 isfixed an arm I31, engaged at its lower end with a face cam I38 on camshaft 40 (also see Fig. 16). A spring I39 connected to arm I31 holds thearm against the face of cam I38. While arm I31 is riding on the flatportion of face cam I38, shaft I33 and its member I 34 are incounterclockwise position (Fig. 11), and pin I340. is in lower position,permitting spring I36 to keep dog I32 in engagement with a ratchet toothH20. of the escapement rack, with the hole in dog I 32 abutting the topof pin I34a. Also pin I341; is in upper position, keeping pawl I35 outof engagement with the escapement rack.

During the cycle of cam shaft 40, after the punching and printingoperation has been com-- pleted under control of cam 88 (see Fig. 21),the bump on face cam I38 rocks arm I31, its shaft I33, andmember I34thereof clockwise, raising dog I32 free of the escapement rack andcausing pin I341; to lower pawl I 35 into a tooth notch of escapementrack. The initial position of the rack with respect to the nose of pawlI35 is such that when the pawl is rocked downwardly, the nose moves intoabout the central point of an interdental notch (Fig. 14) of the rack,and as dog I32 releases the rack, spring motor M effects movement to theright of the rack (and the card carriage) for about half a tooth spaceuntil arrested by the nose of pawl I 35. At this point, the nose of dogI 32 is in such position that upon subsequent downward rocking of thedog, the nose will move into the tooth notch to the left of the onepreviously engaged by the dog. When the cam bump of cam I38 rides oflarm I31, shaft I33, and member I33 thereof are returned counterclockwiseby spring I39, causing pin I34b to release pawl I35 from the rack andpermitting spring I36 to rock dog I32 downwardly to seat its nose in thenext notch. The latter now moves substantially another half a toothspace until arrested by dog I32. The total escapement step of rack I I2is one tooth space. Each tooth space is equal to the width of a cardcolumn, so that each single escapement step causes the card carriage tomove the card to the right as viewed in Fig. 11, or to the left, asviewed in Fig. l, for one column width, thereby bringing the next cardcolumn, following the one previously punched, to operating position withrespect to punch slide 65.

Thus far, punch and type selection, punching and printing, andcolumn-by-column escapement feed of a card upon depression of acharacter designation key I2 have been explained.

It may be noted here that depression of the x and 12 index position keyspositions the punch couple 6165c at the X and 12 index positions of acard column. In these two latter positions, all of the types 15 are tothe left of printing hammer 801) (Fig. 4) so that while the X and 12positions of card columns are punched, no corresponding printing iseffected.

The operations effected by depression of space key I2-S will now beexplained.

Space key operation.-Depression of space key I2--S (Figs. 1 and 6)effects an escapement step or single column feed of the card withoutaccompanying punching, printing, or other operation on the card.Depression of the space key acts through a connected lever I3 to raisevertical slide I4S (Figs. 6 and 9). Intermediate its length, slide I4-Shas a lug I4'--S on which one end of a lever I42 rests. Lever I42 isrotatably mounted on a stud I43 and the end opposite lug I4'S is hookedover an arm I44 fastened to shaft I33 (Figs. 4 and 9). As slide I4-Srises, its lug I4'-S rocks the right hand and of lever I42 (as viewed inFig. 9) upwardly, depressing the other, hook end to effect clockwiseaction of shaft I33, (as viewed in Fig. 11) against resistance of springI39. The clockwise action of shaft I33 results in half-.a-step ofadvance of the card carriage, as previously explained. Upon release andreturn of space key I4-S, the parts operated thereby reverse theirdirections and shaft I33 returns counterclockwise (Fig. 11), completingthe escapement step. Thus, each operation of the space key effects onecard column advance of the card carriage. Space key slide I I-S is notconnected to any horizontal slide' 2|, and therefore, has no connectionto punch selecting or operating means and does not initiate a cycle ofcam shaft 46.

. Release key operation-The purpose of release key I2-R (Figs. 1, 5, and11) is to cause a feed of. the card, from whatever column position itmay be in with respect to the punch slide 65, to the last columnposition, from which the operator may remove the card. Upon depressionof release key I2-+R, the lower end thereof strikes the lug I45 of thehorizontal arm of a bell crank lever I45 freely pivoted on a stud I46.The other, vertical arm of. lever I45 engages a pin I41 at one end of ahorizontal slide I48 (also see Fig. 9). The slide is guided by studs I48with which the slide has tight frictional engagement for frictionallymaintaining the slide in its adjusted positions. The right hand end(Fig. 11) of slide I48 is turned upwardly to engage one arm I49a (alsosee Fig. 14) of a horizontal bell crank lever I49 pivoted on a stud I56. A spring friction washer I5I surrounding stud I50 abuts lever I49 tomaintain it in any adjusted position. Arm I49a lies under escapement dogI32 and normally to the right of a V-shaped cam lug I32a thereof, asindicated in Fig. 11. Upon depression of release key I2-R, its lower endstrikes lever I45, rocks the latter clockwise (Fig. 11), causing thelower endof the lever to act on pin I41 for moving slide I48 to theleft, as viewed in Fig. 11, or to the right, as viewed in Fig. 9, andthe upwardly formed right hand end of the slide thereupon rocks leverI49 clockwise (Fig. 9). As a result, arm I490, engages cam projectionI32a'to raise dog I32 until the upper edge of arm I49 is directly underthe apex of the V-shaped cam projection I320. as indicated in Fig. 14.As dog I32 was lifted, while pawl I35 remained in released position,escapement rack I I2 and the card carriage move to the right (Figs. 11and 14) freely to the last column or card removing position. As thispoint is approached, a pin I52 on rack (I2 strikes the downwardly bentend I49 of arm H941, and returns lever I49, slide I48, and bell cranklever I45 to normal positions.

Ribbon feed Referring to Figs. 1, 2, and 3, ink ribbon R is wound on apair of spools I54 and I55 rotatably carried by opposite end portiom ofa shaft I56 mounted on the fixed bracket I 51 located between thespools. At the printing position is located a fixed ribbon guide plateI58, which projects freely through card slot 65a of punch slide 65 andbetween the rubber platen 11 and below the normal, raised, positions ofthe lower ends of types 15. Plate I56 has a hole I58a (see Fig. 3)located at printing position to permit the type at printing position tofreely move downwardly therethrough. The ribbon R comes off spool I54,around a guide roller I59 (Fig. 2), under plate I58, around a beveledcorner of the plate, over and across the plate to the opposite beveledcorner around the latter and under the plate, and around another guideroller I59 to the other ribbon spool I55. In its course from the lattercorner edge of plate I56 to spool I55, the ribbon passes directly belowhole I58a in the plate in position to coact with the type at printingposition for effecting an imprint on the card (also see Fig. 8).

Spools I54 and I55 have their adjacent flanges in the form of ratchetsI54a and I55a. Coacting with ratchets I54a and I55a are feed pawls I66and I6I pivotally carried by arms I62 and I63 fast to shaft 85 of thepunch and printing operating assembly 688I). The tails of the feed pawlsare engaged with opposite arms of a feed reversing lever I64 fast to thelower end of a shaft I65 passing through bracket I51. The upper end ofshaft I65 carries an arm I66 at right angles to the lever I64 andconnected to a spring I61 which holds the shaft I65 and its arms ineither of opposite angular position to which it may be shifted. Oppositearms of lever I64 are slotted to form passageways for the ribbon. When arivet I68 carried by each end of the ribbon reaches a passageway inlever I64, it cannot pass therethrough and turns the lever from oneangular position to its other angular position. In the angular positionof lever I64 shown in FigS.'2 and 3, the arm thereof abutting the tailof feed pawl I69 is in retracted position, permitting a spring I69 toengage the nose of the pawl with ratchet I54a of spool. I54, while atthe same time, the other arm of the lever is holding pawl I6I releasedfrom teeth I55a. When the angular position of lever I64 is reversed,pawl I60 is disengaged while pawl I6I is engaged, thereby reversing theribbon feed. Upon each operation of shaft 85 of the punch operatingassembly 688Il, arms I62 and I63 rock downwardly, causing the feed pawlthen engaged with the ratchet flange of its associated ribbon spool tofeed the latter.

Verifying operation The punching and printing operations have beenexplained. The machine may be operated alternatively, for verifying acard. By verifying a card is meant the testing of the accuracy ofpunchings in a previously punched card. During the punching operationand printing, the operator reads the data from a record sheet or othersource and depresses the keys I2 corresponding to the data and performsthe other indicated operations such as space or release, to perforatethe card with coded designations corresponding to the data and to causethe printing means to print an interpretation of the punching on thecard itself, in the manner explained before. During verifying operation,the operator again reads the same date on the record sheet or areproduction thereof and repeats the operations of keys I2 as in thepunching and printing of this data. If the columns of the card have beencorrectly punched, the verifying operation will feed the card to theeject or last column position column-by-column. If any column of thecard has been incorrectly punched, the verifying operation will, uponacting on this column, immediately and continuously eject the card toeject or last column position, and the operator will remove this cardand segregate it from the correctly punched and verified cards.

To set the machine for verifying operation, hand knob 04 (Figs. 1 and 6)is turned until its index 04a points to the legend Verify. In turningknob 04 to this position, the eccentric portion 03a of its shaft 03coacts with studs 02 of pressure plate to move the latter towards theright to the retracted position indicated in Fig. '1, in which theforward end of the pressure plate is removed from above the top of punch61 and located directly above but at a distance from transverse pin 01aof the punch. In this retracted position of pressure plate 00, itshammer portion 00b is also withdrawn from above the head of the type 15at printing position, so that printing will not be effected when thepressure plate is depressed.

Referring to Figs. 4, 7, and 8, punch 61, intermediate its length, has aforwardly projecting pin 01b passing through the forked end of a leverI10, pivoted on stud "I to punch slide 65. The opposite end of lever I10is connected by link I12 to one end of a bell crank I13, pivoted to thepunch slide, and having its other end pivotally connected to a bar I14having a horizontally elongated slot I14 through which the shanks ofstuds I15, fixed to the punch slide, pass to mount bar I14 for slidablemovement lengthwise of the punch slide. The lower edge of bar I14 isformed with teeth I14a spaced correspondingly to the spacing of theindex positions 0 to 9, X, and 12 of a card column. Between bar I14 andpunch slide is a light spring I10, yieldably forcing the bar towards theright. This spring force is transmitted by bar I14 to bell crank I13,link I12, and lever I10, tending to rock lever I clockwise. The forkedend of lever I 10 presses on pin 01b and thereby constantly tends todepress punch 01, but with the stripper plate 60 at its normal clockwiselimit (Fig. 13), the engagement of lip 00a of the stripper plate withpin 01a prevents depression of the punch by lever I10.

With a card column at operating position within card slot 85a, to verifythe accuracy of the punching in the card column, the operator depressesa designation key corresponding to the designation 9 to 0, X, or 12, theperforation for which should be in the column if the latter wascorrectly punched. Depression of the designation key initiates a cycleof cam shaft 40, in the same manner previously described, during whichcam (Figs. 15, 16, 17, and 21) causes punch slide 05 to be shifted,along the column in operating position, to the key-selected position inwhich punch 01 is above the index position corresponding to thedepressed key. Cam 1I (also see Fig.

4) then operates to cause alining and locking tooth 14a to enter thenotch 10a of alining rack 10, fixed to slide 05, to lock the latter inthe keyselected position. Cam 00 next effects reciprocation of link 00to oscillate the punch-operating assembly. When the machine was set forpunching, the pressure plate 00 of the punch-operating assemblywasengaging the head of punch 01, as indicated in Figs. 12 and 13; hencedownward movement of the punch-operating assembly caused pressure plate00 to positively move the punch down through its complete down-stroke toperforate the card. During such operation, lever I10 merely followed pin01b of punch 61 but had no influence on the punch. Now, with the machineset for verifying, pressure plate 00 has been retracted from above thehead of punch 01 and downward movement of the punch-operating assemblycauses the pressure plate to move idly downward to the position shown inFig. 7, without affecting the punch. At the same time, stripper plate 00is moving down, permitting the punch 01 to follow under the influence ofspring-actuated lever I10. The punch is thus depressed under theinfluence of the lever I10 alone, as the punch-operating assembly 00-00moves downwardly. As lip a of stripper plate 00 rocks downwardly, pin01a of punch 61 and, therefore, the punch itself may move downwardlyunder the yieldable pressure of lever I10 on pin 01!) of the punch. Ifthe card collnnn has been correctly punched with the designationcorresponding to the operated designation key I2, the card will have aperforation under punch 01, permitting the punch to move freely throughthe perforation and into die hole d of punch die 650. If the card columnis incorrectly punched, it will not have a perforation but a blank,solid portion, below punch 61. Since the pressure of lever I10 on pin61b of the punch results from light spring I16, this pressure isimpositive, light, and yielding, causing the punch to be stopped by theunperforated portion of the card without penetrating the latter.

Before stripper plate 00 is rocked to lower its lip 00a and permitdepression of the punch, a tooth I14a of bar I14 is opposite a pin I18at the end of the horizontal arm of a bell crank I19, as indicated inFig. 4. When the card column is accurately punched, lever I10 movespunch 01 through the correct perforation, to its lower limit. As punch61 thus moves to its lower limit, lever I10 concomitantly rocksclockwise, permitting bar I14 to move under the influence spring I16,its full distance to the right; i. e., until stopped by engagement ofthe left end of its slot I14 with the shank of a stud I15. This movementof bar I14 is equal to that between successive teeth of the bar, againlocating a tooth 0f the bar above pin I10. When the card column isincorrectly punched, punch 01 is stopped by an unperforated surface ofthe card, permitting spring I16 to move bar I14 only about half thedistance between successive teeth of the bar, thereby locating a notchI140. of the bar substantially above pin I10 of lever I19.

The lower end of lever I19 is connected by a link I00 to one end of'abell crank lever IOI urged clockwise (Fig. 4) by a spring I02. The otherend of lever IOI rides on the periphery of a disk I03 (see Figs. 4, 8,9, 16, and 21) fast to cam shaft 40 and provided with a cam notch I03a.While lever IOI is riding on the circular portion of disk I03, springI02 cannot rock lever I19 clockwise.

Iili

During the cycle of 0am shaft 40, cam 89 rocks stripper plate 68 tolower its lip 68a to the position indicated in Fig. '7. This action oflip 680. permits punch 61 to move through a correctly punched hole inthe card or to be stopped by the card surface if the punching isincorrect. In the case where the correct hole is punched in the card,the punch moves to its lower limit accompanied by shifting of slide barI14 a full step to the right (Figs. 4 and 8) to locate a tooth thereofabove pin I18. In the event the card column is inaccurately punched oris not punched in the intended index position, punch 61 is arrested bythe surface of the card, accompanied by a halfstep of movement of barI14 to the right (Fig. 4) to locate a notch between a pair of teeth I14aabove and substantially in position to receive pin I18. After thedownward stroke of the punchoperating assembly has been completed andwhile this assembly is idling (see Fig. 21), the notch I 83a of disk I93comes under the follower end of lever I8I. If the card column wascorrectly punched, the flat ofa tooth I14a will be above pin I19, andalthough notch I83a is under the follower end of lever I83, spring I82is able to move the lever clockwise only a slight extent before pin I18abuts the tooth I14a above it. However, if the card column wasincorrectly punched, an interdental notch of bar I14 will be above thecenter of pin I19. Spring I82 is then effective to rock lever IBI itsfull clockwise extent, as indicated in Fig. 3. During this action, leverI19 is rocked similarly and the left side of pin I18 encounters thecorner of the tooth "411, located to its left, and cams against thetooth corner to move bar I14 slightly to the left as it enters theinterdental notch. As a result, bar I14 is looked, as shown in Fig. 8,after a slight return movement to the left. As an incident to thisslight return of bar I14, lever I13 is rocked clockwise, and throughlink I12, rocks lever I19 slightly counterclockwise. Consequently, theforked end of lever I19 raises punch 61 slightly, to bring the lower,cutting edge of the punch at a clearance distance from the surface ofthe card. The purpose of this is to prevent contact between the punchand the card during the release operation which accompaniesdetermination of an incorrect punching, as will be explained, therebyavoiding any possibility of damaging or dulling the punch during therelease of the card.

When the card was incorrectly punched, pin I19 of lever I19 moved fullyinto a notch between teeth I'Ma of bar I14, as explained above.Concomitantly with, and as a result of this, lever IilI rocks its fullextent clockwise, as indicated in Fig. 8. As lever I8I moves to itsclockwise limit, a projection I8Ia thereof (Figs. 4, 8, and 9) strikesarm I491) (Fig. 9) of escapement release lever I49 to rock the latterclockwise. Arm I49a of lever I49 thereupon moves under projection I32a(Fig. 14) of dog I32, camming the dog upwardly to release it from rackII2. As in the release key operation, pawl I35 remains disengaged fromthe rack. Due to its frictional mounting lever I49 remains in actuatedclockwise position while lever I8I is returned as cam notch I83a passesthe follower end of the latter lever. The notch I830. traverses andpasses lever I8I while the dwell of cam 88 is engaging pin 81a of lever81 which operates the punch-operating assembly (see Fig. 21). Hence,during the punching operation of the machine, the notch I83a will notmove under lever I8I until the punch is fully 1| depressed and haspunched a hole. The bar I14 will accordingly have moved a full toothdistance to the right, preventing effective rocking of lever I19. Thecam notch I83a will then pass lever IBI while the punch is fullydepressed, so that lever I8I will have no tendency to effect releaseoperation when the machine is set for punching.

During the verifying operation, and upon finding of an incorrectpunching on a column, lever I 49 was moved clockwise to releaseposition, in which it remains after lever I BI is returned, as explainedbefore. After the release operation starts, and after lever I8I has beenreturned, the escapement cam I38 acts (see Fig. 21). As a result, pawlI35 is momentarily lowered into engagement with rack II2, temporarilyarresting release operation. The pawl I35 is soon lifted, and therelease operation resumes to move the card to last column or ejectposition, from which the operator removes it and segregates it from theaccurately punched and verified cards. When rack II2 moves to its lastcolumn position, pin I52 thereof strikes downwardly bent end I49 oflever I49, returning the latter to normal position. The dog I32,thereupon, also reengages rack teeth I I2a.

In above manner, when a card column is found by the verifying operationof a key I2 to be incorrectly punched, the card is ejected or moved toits eject position.

If the verifying operation finds a correctly punched column, a tooth ofbar I140. on punch slide 65 prevents effective clockwise action of leverI BI projection I8Ia does not operate release lever I49, and cam I33subsequently causes member I34 to effect the regular column escapementof the card carriage, bringing the next card column to verifyingposition at card slot 65a of punch slide 65.
